Common to all PLC isozymes, PLCG1 consists of an N-terminal PH domain, which translocates PLC to the plasma membrane and binds PIP3[1]; four EF hands; an X and Y catalytic region comprising the TIM barrel; and a C-terminal C2 domain. Specific to the PLCG isozymes is a large separation between the X and Y domains consisting of a split PH domain, tandem SH2 domains, and an SH3 domain[2]. The SH2 domains bind phosphorylated tyrosine residues on target proteins via their FLVR sequence motifs, activating the catalytic function of PLCg; and the SH3 domain binds to proline-rich sequences on the target protein [2]. PLCG1 can be activated by receptor tyrosine kinases (RTKs) and non-receptor tyrosine kinases. For example, when activated, fibroblast growth factor receptor 1 and epidermal growth factor receptor are RTKs that have phosphorylated tyrosines, which provide docking sites for PLCg1 SH2 domains[2]. The activated RTKs phosphoylate PLCg1 at tyrosines located at position 472, 771, 775, 783, and 1254[3]. Non-receptor tyrosine kinases interact with PLCg1 in large complexes at the plasma membrane. For example, in T cells, Lck and Fyn (Src family kinases) phosphorylate immunoreceptor tyrosine-based activation motifs (ITAMs) on the T-cell antigen receptor (TCR). The phosphorylated ITAMs recruit ZAP-70, which phosphorylates tyrosines in LAT and SLP-76. PLCg1 binds to LAT through its n-terminal SH2 domain and to SLP-76 via its SH3 domain[2].Lbates2008 (talk) 01:47, 9 March 2017 (UTC)[reply]


I think you should've posted your draft in the sandbox. I think. Besides that, I didn't really understood the second sentence of the second paragraph. If you could fix the flow that would be awesome. Ncameron2013 (talk) 19:07, 12 March 2017 (UTC)NCameron2013[reply]


I agree with the above Wikipedian that you'd have done edits in the sandbox. About the edits, I think you have done a good job overall with adding detailed information about structure in straight and simple words with proper citations. KP 0503 (talk) 06:22, 12 April 2017 (UTC)kp0503[reply]
